| 1 | 科尔沁沙地东南部地区主要植物叶片性状及其相互关系显示文摘选取科尔沁沙地东南部地区23种主要植物,将其划分成草本、灌木和乔木3种生长型,并分别测定其叶片鲜重(FW)、干重(DW)、叶干物质含量(DMC)、面积(AR)、比叶面积(SLA)和厚度(TH)等6项叶片性状因子。结果表明,草本植物的叶片性状比灌木和乔木变异大;平均SLA和DMC草本<灌木<乔木,DW反之,而TH则没有明显的变化。方差分析发现,除DW和TH外,SLA和DMC在不同生长型中的变化显著,并且SLA与DMC呈显著负相关,说明SLA和DMC是在植物资源利用分类轴上划分植物种类的最佳变量。对于厚度,还需进一步进行研究。 | 刘金环 曾德慧 Don Koo Lee | 2006 | 生态学杂志2006,25,8: | 137 |
| 2 | Assessment of Pb uptake,translocation and immobilization in kenaf (Hibiscus cannabinus L.) for phytoremediation of sand tailings显示文摘The potential of kenaf (Hibiscus cannabinus L.) for phytoremediation of lead (Pb) on sand tailings was investigated.A pot experiment employing factorial design with two main effects of fertilizer and lead was conducted in a nursery using sand tailings from an ex-tin mine as the growing medium.Results showed that Pb was found in the root,stem,and seed capsule of kenaf but not in the leaf.Application of organic fertilizer promoted greater biomass yield as well as higher accumulation capacity of Pb.In Pb-spiked treatments,roots accumulated more than 85% of total plant Pb which implies that kenaf root can be an important sink for bioavailable Pb.Scanning transmission electron microscope (STEM) X-ray microanalysis confirmed that electron-dense deposits located along cell walls of kenaf roots were Pb precipitates.The ability of kenaf to tolerate Pb and avoid phytotoxicity could be attributed to the immobilization of Pb in the roots and hence the restriction of upward movement (translocation factor < 1).With the application of fertilizer,kenaf was also found to have higher biomass and subsequently higher bioaccumulation capacity,indicating its suitability for phytoremediation of Pb-contaminated site. | HO Wai Mun ANG Lai Hoe LEE Don Koo | 2008 | Journal of Environmental Sciences2008,20,11: | 14 |

| 11 | Effects of Temperature on Photosynthetic Rates in Korean Fir (Abies koreana) between Healthy and Dieback Population显示文摘The present study was carried ou t on natural Korean fir forests (Abies koreana) growing in Mount Halla in Jeju Island, Korea (33°13-36'N and 126°12-57'E). Mount Halla is the highest mountain (1950 m a.s.l.) in South Korea. On the Korean fir forests near the top of Mount Halla in Korea, we established permanent plots between dieback and healthy population. Each permanent plot includes both dieback and relatively healthy Korean fir individuals. Three sites in this study showed similar altitude, topographic position, aspects, slope, diameter at breast height, average height and ages. Net photosynthetic rates (PN) on different temperature regimes were evaluated to explain the forest dieback phenomenon on Korean fir populations. Light response curves were determined on three different temperature regimes:15°C, 20°C and 25°C. The irradiance response curve showed higher values in lower air temperatures. Generally, irradiance response curves of healthy Korean fir populations were higher than the dieback population at all sites. | Su Young Woo Jong-Hwan Lim Don Koo Lee | 2008 | Journal of Integrative Plant Biology2008,50,2: | 1 |
| 12 | Leaf traits and their interrelationship of 23 plant species in southeast of Keerqin Sandy Lands,China显示文摘Six leaf traits,i.e.,fresh mass(FM),dry mass(DM),leaf dry matter content(DMC),area(AR),specific leaf area(SLA)and thickness(TH)from 23 plant species in the southeastern Keerqin Sandy Lands,China were measured.The results show that leaf traits of herbs were more diversified than those of shrubs and trees and aver-age SLA tended towards a decreasing trend from herbs to shrubs to trees.On the contrary,DMC and DM show an upward trend from herbs to shrubs to trees.No apparent difference was found in TH.Except for DM and TH,there were significant variations in SLA and DMC among three different growth forms.Moreover,a significant correlation was found between SLA and DMC.It is concluded that SLA and DMC could be used to predict species position along a resource use gradient. | Jinhuan LIU Dehui ZENG Don Koo LEE Zhiping FAN Lei ZHONG | 2008 | Frontiers in Biology2008,3,3: | 0 |
| 13 | The Survival and Vegetative Growths of a 60 Month-Old Tropical Rainforest Tree Species Trial Established under a Hopea odorata Nurse Stand at an Ex-Tin Mine in Peninsular Malaysia显示文摘AFoCo(Asian Forest Cooperation)Project in 2011 has funded a research and development project in Malaysia for enriching a mono-species stand established in an ex-tin mine.The project covered only for a period of 12 months.A study plot of 1 ha size was established in TTAC(Tin Tailings Afforestation Centre).Twenty indigenous tropical rainforest tree species were planted and their five year-old survival count,diameter and H(top height)growths are reported in this study.Some of them are red list species of IUCN(International Union of Conservation of Nature).The survival of the 1 ha planting trial was 53%.Mortality of the tree species is mainly caused by wild boars.The tropical rainforest tree species in this planting trial had similar growth to those planted at good mineral soils.This paper also documented the tending treatments which were implemented during post-planting that have contributed to healthy growth of the mixed-species stand.The mixed-species stand is being properly tended till to-date and hence sustained growth of the stand is anticipated. | Lai Hoe Ang Wai Mun Ho Lai Kuen Tang Ho Sang Kang Don Koo Lee | 2018 | Journal of Environmental Science and Engineering(B)2018,7,4: | 0 |
